Incoming Signal Strength Check

Motorola 3416 DVR from Comcast.
Is there any place in a menu from the box to check incoming signal strength? If so, where? And then last, what should it be for a good signal?
I want to do a comparison. Sometimes the pq is good but not outstanding, other times (usually on weekends, especially Sundays), it is "oh my god, wow!"(HD channels of course on both).
Just looking for an easy way to check incoming strength to see if there is a variable.

thanks

edit: oops, I just realized that this is probably posted in the wrong sub forum. Looks like I should have put it in "cables and connections". Sorry about that.
